Aha!  I think you hit the nail on the head.  `ldd` revealed that the LDC
binary has dynamic dependencies on libphobos2-ldc-shared.so and
libdruntime-ldc-shared.so.  So that explains that.

So that's one less reason to ditch dmd... but still, I'm tempted,
because of overall better codegen with ldc, esp. with compute-intensive
code.
